BB's festival rave

The Big Brother housemates put the strain of nominations and tomorrow's looming eviction out of their minds as they let their hair down at a party.

The summer festival rave was laid on for the group last night as a reward for successfully completing a Glastonbury-themed task.

The Channel 4 reality TV show contestants were treated to henna tattoos, tie-dye outfits, goats cheese, and longed-for music to liven the event.

Ahmed danced like a dad at a wedding, Nadia shimmied seductively and Victor waggled his knees as Marco displayed some bottom-thrusting moves to pop hits Dancing In The Moonlight, Cosmic Girl and the Superman Lovers' Starlight.

Michelle and Stuart smooched during the last dance - Don McLean's Vincent - while Ahmed, partnerless, sauntered into the garden, settled into a hammock and starred at the stars while mouthing the lyrics.

Earlier yesterday they succeeded in the final stage of the Glastonbury task - a "folk off" contest in which they had to compose and perform folk songs.

Dressed up in Arran jumpers and fake beards, they split into two teams and sang their songs accompanied by a guitar and tambourine.

The task took their minds off tomorrow night when either Nadia, Marco or Michelle will be evicted.

Becki told Big Brother she felt guilt-ridden about choosing Michelle.

New housemate Becki secretly nominated her by giving her a kiss on both cheeks.

On hearing that she was up for eviction, Michelle threw a tantrum and threatened to walk out.

Explaining her choice, Becki said: "She was the only person who I didn't feel any warmth from. Although she was pleasant I just didn't feel something.

"It's really awful the way I did it. It takes me back to Jesus and Judas."

Marco and Michelle are hot favourites to get the boot, while Nadia's odds have drifted.

"Punters think the hand clapper and stroppy Geordie are more likely to go than the Portuguese transsexual," said a Ladbrokes spokesman.

"We were initially of the opposite opinion until money forced us to drastically change the odds. This could be one of the most open Big Brother evictions we've seen."
